-Does 4-methylimidazole have tumor preventive aittvicy in the rat?Murray FJ.SourceMurray and Associates, San Jose, CA 95138, USAAbstract4-Methylimidazole (4-MEI) is found in a wide array of food productsThe National Toxicology Program (NTP) recently conducted a two-year feeding cancer bioassay of 4-MEI in B6C3F(1) mice and F344/N ratsIn rats, NTP found  equivocal evidence of carcinogenic aittvicy  in females based on increased incidences of mononuclear cell leukemia and  no evidence of carcinogenic aittvicy  in malesHowever, dose-related, statistically significant decreases in multiple tumors were observed in both male and female rats exposed to 4-MEI in the NTP bioassayFor example, 4-MEI was associated with a 25-fold decrease in the incidence of mammary tumors among high dose femalesNTP noted briefly that the decreases in certain tumors, including mammary tumors, were greater than could be attributed to body weight aloneThe present paper provides a more detailed evaluation of the evidence that 4-MEI exhibits tumor preventive aittvicy in the rat based upon the results of the NTP bioassayReduced body weight offers a partial explanation for the reduction in tumors, but does not appear to be the primary cause of the decreased tumor incidences, indicating that 4-MEI itself may possess an ability to prevent tumor formation.Copyright a9 2010 Elsevier LtdAll rights reserved.+====== shack ntp setup ======
